I was horribly indecisive with the Series 3 and bought almost every band (and sent it back again). In the end I made a decision I regretted. I bought the watch with the Indigo Swift, but sold the strap and bought the Feu Epsom to replace it.
The Indigo Swift was elegant but a bit boring. But it was also insanely soft and comfortable. The Feu Epsom was great looking, but it stained easily and was very stiff and not comfortable. I ended up selling that strap, too, and now I just use the Hermes Sports strap.
I think I’m coming round to getting the Indigo Swift this time. As much as I love the clown strap, I think it’s going to be difficult to look after. White is a dangerous colour to wear.
